     编者前言:2001年,美国游泳教练员协 会在新奥尔良举办了世界游泳教练员讲习班。 福布斯·卡莱尔在讲习班上播放了他录制的一 套名为《爬泳技术的发展》录像片。在这部 录像片中,卡莱尔介绍了游好爬泳应注意的 8原则。木刊现将这8条原则和参考译文同 时刊出,以飨读者。如读者对这8条原则有 更好的译法,请将译文寄我刊,我刊将选登 来稿以便更准确地理解卡莱尔的8原则。
        任何一名选手都有改进身体流线型姿势 的余地。改进身体流线型姿势的重要性不言 而喻。下述8原则中的任何一条,都会使你 受益。       a.  Keeping  the  body  horizontal  and  not raising the shoulders  in  concert  with  arm  en- tries. The body should only be rotated on a hor izontal, longitudinal axis.       1.入水时,身体应保持水平姿势,肩 部不应上抬。身体只能在水平方向上,围绕 身体纵轴转动。       b. Keeping the head down, looking  at the bottom and then to the side of the pool when breathing, so that rotation on a horizontal, lon- gitudinal axis  is  achieved. It  is  detrimental  to streamlining to look forward and and/ or to raise the head at any time, particularly when breathing.       2.要低头,目视池底,吸气时,目视池 侧,以便身体在水平方向上围绕其纵轴转动。 目视前方,或抬头,特别是呼吸时抬头,会 破坏身体的流线型姿势。       c. Keeping  the  legs  and  kick  within  the body shadow  so  that  form  resistance  in  mini mized. The only  time  the  legs  should  emerge from  the  position  of  maximum  streamline  is when detrimental effects  are more than  offset by arm propulsion gains。 3 要在身体投影截面内打腿,以尽量减小 形状阻力。一旦打腿动作超出身体姿势的流线 型范围,会抵销划臂动作产生的推进力。     d. Reducing downward  pressure  after the arms enter the water and achieving a horizontal pull component  earlier. Bending  at  the elbow, immediately  after entry, would  assist  in faster directional  force  change.  If   this   could   be achieved there is every likelihood that  stream- lining will be better maintained.     4.臂入水后,尽量避免下压,并设法尽 早获得水平分力。入水后立即屈肘有助于更 快改变用力方向。如能做到这点,将有助于 身体保持流线型姿势。       e. Rotating the hips and shoulders together to the same degree  in  a streamlined  position. This will reduce form resistance.     5.为保持流线型姿势,髓部和肩部应同 步转动。如此转动有助于减少形状阻力。       f. Allowing the kick to rotate on a longitu- dinal axis in concert with hip rotation. A  con- centration on vertical kicking increases form re- sistance whereas  rotation  has  the  potential  to decrease it without any loss in forward and velocity.     6.为配合转髓动作,应围绕身体纵轴做 打腿动作。只做上卜打腿会增大形状阻力, 然而通过转动打腿,不仅不会减慢游速,并 可减少形状阻力。       g. Aligning the upper arm of the pull and recovery with  the line of  the shoulders  to  in- crease the musculature used to generate force as well as  maintain  the  integrity  of  the shoulder joint. An emphasis on, or tolerance of, internal rotator  muscle  group  activety  will  eventually cause problems. This proposal will  introduce  a greater  role  for  the  external  rotator  muscles during the pull.     7.划水和移臂时,上臂靠近肩线既便于肌 群发力,又可避免肩伤。内旋肌群负担过重将 造成伤害。建议划水时尽量发挥外旋肌作用。     h.  Maintaining     streamlined   feet   when kicking so that drag is not created. However, it must be realized that a“braking’action may be a corrective movement for some other error.       8.打腿时应注意脚部的流线型姿势,以 免增加阻力。然而必须知道有时“制动”动 作可矫正其他技术错误。
